ganglia配置
gmetad配置
在ganglia安装目录执行如下操作
cp -a gmetad/gmetad.init /etc/init.d/gmetad
chkconfig –add gmetad
chkconfig –level 345 gmetad on
gmetad -t | tee /usr/local/etc/gmetad.conf
mkdir -p /var/lib/ganglia/rrds
chown nobody:nobody /var/lib/ganglia/rrds
配置gmetad.conf
1.修改gmetad.conf 中 data_source
data_source "hadoop201" hadoop201
gmond配置
cp -a gmond/gmond.init /etc/init.d/gmond
chkconfig –add gmond
chkconfig –level 345 gmond on
gmond -t | tee /usr/local/etc/gmond.conf
配置gmond.conf
修改 cluster中 name 为在gmetad.conf 中的data_source
cluster {
name = "hadoop201"
owner = "nobody"
latlong = "unspecified"
url = "unspecified"
}Ganglia-web环境部署
tar xvzf ganglia-web-3.6.2.tar.gz -C /var/www/html/
cd /var/www/html/
mv ganglia-web-3.5.12 ganglia
chmod -R 777 /var/www/html/ganglia
cd /var/www/html/ganglia
cp conf_default.php conf.php
vim conf.php
conf.php中有些默认配置和以上设置不一样的需要进行修改：
# Gmetad-webfrontend version. Used to check for updates.#$conf['gweb_root'] = "/var/www/html/ganglia";
$conf['gweb_confdir'] = "/var/www/html/ganglia";

问题及解决方式
编译rrdtool 错误

ganglia编译必须依赖rrdtool，而rrdtool安装不同机器可能出现莫名的安装错误，此时如果机器可以连接网络可以使用 yum -y install rrdtool 方式安装，但此时安装后，编译ganglia时仍然无法找到rrdtool相应的库，此时可以采用如下方法,使ganglia编译安装成功：
下载rrdtool-1.4.8.tar.gz ，解压后，将rrdtool-1.4.8/src/.libs 中相应库拷贝到如下目录：
home/hadoop/为我本机rrdtool-1.4.8所在路径：
cp /home/hadoop/rrdtool-1.4.8/src/.libs/.so /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/.libs/*.a /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/.libs/*.la /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/rrd*.h /usr/local/include
